    Thin and simple

      I recently ordered this as a running sports bra - and it definitely won't do the trick for that. But I kept it as a casual, non-impact time bra. It's not super supportive or thick, but does a great job as a basic, comfortable bra. Not for those who need it for running, or jumping.

      Great hot weather sports bra

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Small

      I love this sports bra for hot weather. It is light and thin and breathes really well. That being said, I don't need much support so I'm very happy with it, but I can see how this might not offer as much coverage or support for women with a larger chest.

      Love it!

      • Fit: True to size

      The Wife: I needed a basic sports bra just for yoga and climbing and this met my needs exactly! I don't think it'd be that great for running or more extreme sports where there is a lot of movement but for the purpose of relaxed and more casual athletics this is the sports bra you need!

      great sweat wicking, strange fit

      • Familiarity: I've put it through the wringer
      • Fit: Runs small
      • Size Bought: small

      This bra runs small, the the bottom strap/band is tight. I bought in on sale so I did the old pull&stretch to solve the problem, but beware if you're paying full price!


      • Familiarity: I gave it as a gift but have feedback to share
      • Fit: True to size

      Wife is prego and wanted a comfy bra. bought this in a few sizes so she could wear them as they um..changed. She's stoked on them . Low profile. Comfy

      Great Support but thin

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      So I love this bra great for wearing under a tank top but not as a stand alonne. If you are looking for a good stand alone bra get the Patagonia Active Mesh Bra ( As far as support this bra is great. Also the thin-ness is there to help with breathing. So you don't have a sopping wet bra if you sweat a lot. It also is a great choice for those racer back tanks that you just don't have a bra for. I am a 34 B and the small fits great!

      Very thin fabric

      • Familiarity: I returned this product before using it

      This bra was super comfortable when I tried it on. I got a size S and wear a size 32 B bra and felt like the small fit great. I got it for climbing and wanted to be able to have the option to wear it with nothing over it around people. I felt like the fabric was way to thin, almost as thin as underwear, so I wouldn't be comfortable around people in it because it showed everything. I feel like it would be the perfect bra for running or biking if you are smaller like me because it would keep you cool and wouldn't ever bother you.

      Not for running

      • Familiarity: I returned this product before using it

      While I liked the feel of the fabric, being a 32D/34C I didn't feel this would have enough support for anything more than hiking and hanging out. I returned it for something that could provide support when I'm on the move.
